Re: could it be propped wrong?
boat weight I really don't know, I read something the hull weight was around 5600, I don't know if that was with engine, this Particular hull came with many power options , outboard or sterndrive,and I've seen them online installed with factory 5.7's, as far as weight shift, not sure what can be shifted no one ride in the cabin or up front , the trim tabs hose runs external I'm guessing it should be no problem to shift rams higher I would just have screw holes to patch in my new transom, I'm concluding and agreeing with everyone about the mirage now( lesson learned, ask someone who knows be for buying something you know nothing about)., and taking it somewhere would be time and money wasted, since mods would cost more then a new Aluminium, and they can't add surface area, I looked online props that are larger dia seem to be less pitch, 16x16, assuming I can swing a 16", I'm a bit confused with Tail gunners post, seems then dropping pitch would give me less top end but less slip???is that what I need to consider, I'm guessing I will never see 50+ from this setup, I'm hoping she should run some where 40+, she will do 33-34 now. I certainly do not want to sacrifice my cruise area of 3000-3500, top end would seldom be used, I'm just thinking she could be more efficient through out all her ranges, for all I know 3500 cruise rpm may be way to high, she will fall back and plow @ around 2900-3000, I just figured 454 WOW what a beast. and expect more, I know she is a torque monster. as to trim blow out, she certainly does that, and she never gets to that porpoise state before she blows out,how ever I have had it to a point where she did go a bit faster 36-37 maybe, just before blowing out along the intercoastal, however her RPMs would excede 4600, so I stop trimming when RPMs hit 4600 I would have thought there would have been a rev limiter in the ignition system but guess not, the tach should be correct it's new, the old tach worked and gave the same readings, it was sticking at times you had to thump it. think i may be struggling to find a good prop guy in the area, places that sell props, are just that they sell props with my other boat I had to tell them what i needed and they would go pull it from stock.
